Volunteers from animal welfare groups in the city on Sunday cremated the carcasses of the dogs which were allegedly killed last week in a village in Tiruvallur district.
According to Dawn William, general manager, Blue Cross of India, four volunteers from Save Earth for Next Generation and seven volunteers from Chennai Social Service cremated around 99 dogs on Sunday.
He said he took 21 dogs for post-mortem to the Tamilnadu Veterinary Animal Sciences University on Saturday but could not take the rest because of the rains.
Mr. Williams said on Saturday, one of the residents of the village tipped them off about the alleged killings and he found the dogs buried in the bed of the river in the village. “The other reason for cremating the dogs was to prevent the pollution of ground water as the burial site was barely 50 metres away from a borewell,” Mr. Williams said.
